How can the cytoskeleton of a cell be described?
question 8 options:

framework and anchor for organelles

selectively permeable series of membranes

semifluid material

transport system

framework and anchor for organelles

Explanation:

Cytoskeleton are made of three main filaments including actin filaments, microtubules and microfilaments. Microfilaments are flexible double strands of the protein actin  that are of different proteins which give  mechanical support. Important functions include:They lead the intracellular movement of organelles  and molecules .They stabilize mechanically the plasma membrane.

Microtubules are rigid hollow cylinders of the proteins α- & β-tubulin . They are responsible for the position and stability of ER and  Golgi-Apparatus . They help to divide & move chromosomes during mitosis  and also organize the growth of the cell wall . Actin filaments are robe like fibres of different proteins which give mechanical support.

i am going to guess that it is co2.
